Solution Overview
Problem
LTE User Equipment does not effectively process omnidirectional and beam-formed reference signals to direct eNodeBs to switch between beamforming and omnidirectional transmission modes, leading to inefficient antenna configuration management in wireless communication networks.
Innovation Solution
A wireless communication device determines the difference in quality between omnidirectional and beam-formed reference signals and selects an omnidirectional network antenna configuration, transmitting this information to the network, which then adjusts its antenna configuration to either beamforming or omnidirectional mode based on the feedback, allowing for dynamic switching between the two.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming transmission modes are used, then signal quality and network performance are improved, but the system cannot adapt to conditions where omnidirectional transmission would be more suitable
Solution Approach 1:
The patent implements dynamic transmission mode selection by enabling the wireless communication device to measure and compare reference signal qualities from both beamforming and omnidirectional antennas, then switch between transmission modes based on current channel conditions. This makes the system adaptable rather than static, resolving the contradiction between optimizing for beamforming performance and maintaining flexibility to use omnidirectional modes when appropriate.
Solution Approach 2:
The patent employs feedback mechanisms where the wireless communication device measures reference signal qualities, determines quality differences, and sends feedback to the network to trigger transmission mode switching. This closed-loop feedback system allows the network to adapt transmission modes based on actual channel conditions, simultaneously achieving high signal quality through beamforming when needed and adaptability to switch to omnidirectional modes when conditions warrant.
2Adaptability or versatility
If the wireless communication device processes both omnidirectional and beam-formed reference signals, then transmission mode switching capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the reference signal processing into distinct components: omnidirectional reference signal measurement and beamforming reference signal measurement. By separating these processing tasks and evaluating them independently, the device can compare qualities and make switching decisions without requiring a completely new processing architecture, thus improving adaptability while managing complexity through modular processing.
3Productivity
If LTE User Equipment processes reference signals to direct eNodeBs to switch transmission modes, then network performance is improved, but the existing LTE UE architecture is insufficient
Solution Approach 1:
The patent enables the wireless communication device to autonomously measure reference signal qualities, determine quality differences between transmission modes, and generate switching recommendations without requiring complex network-side processing or additional infrastructure. The UE serves itself by performing the measurements and making intelligent decisions about when to switch modes, improving network performance while avoiding the need to overhaul UE architecture.
